COAL OUTCROP AND OVERBURDEN MAPPING WITH KELSH PLOTTER

THE TECHNIQUES DEVELOPED FOR MAPPING COAL SEAMS AND OVERBURDEN USING THE KELSH PLOTTER ARE DESCRIBED. APPLICABLE TO TERRAIN TO BE STUDIED FOR HIGHWAY RELOCATION, THE METHOD IS ECONOMICAL, UTILIZING THE SAME PHOTOGRAMMETRIC MATERIALS USED TO PRODUCE THE TOPOGRAPHIC MAP FOR THE RELOCATION STUDY. THE COAL SEAMS WERE DEPOSITED UNDER SWAMPY CONDITIONS, THE BASE DESCRIBING AN APPROXIMATE PLANE WHICH HAS BEEN SUBJECTED TO DIASTROPHIC FORCES. DETERMINATION OF THE DIP AND STRIKE WITHIN THE MAPPING LIMITS IS DONE BY USING EXISTING GEOLOGICAL INFORMATION AND PHOTO INTERPRETATION OF SURFICIAL COAL MANIFESTATIONS. RETRIEVAL OF THE ORIGINAL COAL BASE THROUGH LEVELING THE KELSH MODELS RESULTS IN A SEGMENTED MAPPING OF THE COALS AND OVERBURDEN, EACH MODEL LEVELED TO THE BEST INFORMATION AND CONNECTED TO ADJACENT MODELS IN THE FLIGHT STRIP. /AUTHOR/
